My present invention pertains to wagon brakes, and contemplates the provision of a peculiar and ad vantageous construction the draft animals pull backwardly on the tongue of the wagon as when a grade is being descended.

Other objects and practical advantages of the invention will *be fully understood from the following description and claims when the same are read in connection with the drawings, accompanying and forming part of this specification in which Figure 1is a plan view of so much of a wagon construction trate the preferred vention.

Figure 3 is a fragmentary inverted plan 'view hereinafter explicitly referred to.

Similar numeralsof reference designate 7 corresponding parts in all of the views of the drawings.

The structure illustrated comprises among other elements a front axle 1, equipped with ground wheels 2, and fixedly connected at 3 nected together at to hounds 1. the said hounds 4 being con an intermediate point through the medium of a transverse bar 5,

and being connecte d together at their forward spaced ends by upper and lower plates 6 and7. The said plates 6 and vided at 8 and 9, cident longitudinal 7 are pro respectively, with comslots shown in Figures 2 and 3. Connected at 10 with the cross bar 5 superposed upon the hounds 4 andextending forwardly from the said bar 5 is a metallic bar 11 that is longitudinally slotted as designated by 12.

gitudinally in the formed between hounds l Slidable lon longitudinal guideway the forward portion of the and also between-the plate 6 and 7 is a tongue or pole 13 to the forward portion of whichdraft animals in the conventional manner compatible invention which are hitched manner or in any other with the purpose of my involves the rearward.

tongue or pole 13 movable pin the tongue or pole.

The said is equipped with a re- 14, flexibly connected at 15 to It will also be apparent from Figure 2 that the tongue or pole 13 is sheathed with appropriate metal at 16, and that a vertical aperture 17 is formed in the tongue and also in the lowerand upper portions of the metallic sheathing, said vertical aperture 17. being designed to receive the pin 14 under certain conditions as hereinafter pointed out. Superposed upon the upper plate 6 and movable thereon longitudinally of the wagon is a brake beam 18, the said beam 18 being provided adjacent to its ends with appropriately spaced shoes 19, arranged forward of the peripheral portion of the ground wheels 2. The said beam 18 is interposed between the bar 11 and the plate 6 and is fixedly connected to the tongue or pole 13 through the medium of a vertical bolt 20, the said bolt 20 extending through the slot 12 of the bar 11, through H the brake beam 18 and through the slots 8 and 9 in the plates 6 and 7 and being provided at its, upper end with an approtained out of engageinentwith the ground wheels 2, and hence my improvement will 5 not interfere in anv measure with the forward movement or. control of the wagon. When, however, rearward pull is exerted by the draft animals on the tongue or pole 13, the beam 18-.moving rearwardly with the tongue or pole 13 will bring aboutthe powerful application of the brake shoes 19 to the wheels 2, and the greater the rearward draft on the tongue or pole 13 the more powerfully will the brake shoes 19 be held to the peripheral portions of the wheels 2 for the, efficient braking of the wagon. When it is not desired to apply the brake shoes 19 to the front wheels 2 of the wagon, itis simply necessary for the person in authority to dispose the pin 14: in the aperture 17 in asmuch as when this is done, the pin bringing up against the forward ends of the plates 6 and 7 will effectively prevent rearward movement of the tongue or pole 13 sufficiently far to carry the brake shoes 19 into engagement with the wheels 2.

Notwithstanding the capacity of function ascribed to my improved construction, it

will be appreciated that the construction as rough usage and the shock and jars to which wagon appurtenances are ordinarily subjected.

I have entered into adetailed description of the construction and relative arrangement of the parts embraced in the present and preferred embodiment of my invention in order to impart an exact understanding of the said embodimentin all of its details. I do not desire, however, to be understood as limiting myself to the precise construction and relative arraiwement of parts as disclosed, my invention being defined by my appended claims within the scope of which changes in construction and in arrangement may be made without departure from my invention.

Having described my invention, what I claim and desire to secure by Lettersatent, is

1. In a front wheel wagon brake and in combination, a front axle equipped with ground wheels, hounds connected to and extending forwardly of said front axle, plates arranged above and below and connected to the forward portions of the hounds and having coincident longitudinal vertical slots at points opposite the forward portions of the hounds, a longitudinal bar connected with the hounds at an intermediate point in the length thereof and provided with a longitudinal vertical slot in its forward portion, a tongue movable longitudinally between the hounds and also between the said slotted plates, said tongue having metallic sheathing in opposed relation to the said slotted plates and also having a vertical aperture, a pin flexibly connected with the tongue and adapted to be removably inserted in said apeitures to prevent operative rearward movement of the tongue, a transverse brake beam movable upon the upper slotted plate and interposed between said plate and the longitudinally slotted forward portion of the said bar on the hound, and a bolt extending through the said beam and also to the longitudinal slot in the said bar and through the tongue and also through the longitudinal slot in the lower and upper plates, and movable forwardly and rearwardly with the said beam.

2. In a brake construction for the front wheels of a wagon and in combination, a front axle, ground wheels carried thereby,

hounds connected to and extending forwardly of said axle and having a space between their forward portions, lower and upper longitudinally slotted plates fixed to the forward portions of the hounds, a tongue movable longitudinally between the forward por tions of the hounds and also between the said slotted plates, a longitudinal bar connected with the hounds and having a forward longitudinally slotted portion overhanging and spaced above the uppermost slotted plate. a transverse brake beam movable rcarwardly and forwardly between the slotted portion of said bar and the uppermost slotted plate and equipped with brake shoes opposed to the wheels, and means connecting the tongue and said transverse beam and disposed and movable longitudinally of the wagon in the said slots of the longitudinal bar and the plates above and below the hounds.

3. In a brake construction for the front wheels of a wagon and in combination, a front axle, ground wheels carried theehy, hounds connected to and extending forwardly of said axle and having a space between. their forward portions, lower and up per longitudinally slotted plates fixed to the forward portions of the hounds, a tongue mo able longitudinally between the forward portions of the bounds and also between the said slotted plates, a longitudinal bar connected with the hounds and having a forward longitudinally slotted portion overlranging and spaced above the uppermost slotted plate, a transverse brake beam movable rearwardly and forwardly between the slotied portion of said bar and opposed to the wheels, and means connecting the tongue on said transverse beam and disposed and movable longitudinally of the wagon in the said slots of the longitudinal bar and the plate-3 above and below the hounds: the said tongue being provided in advance of the slot ed plates with a vertical aperture, and being equipped with a pin flexibly connected with and removably socheted in the tongue and adapted when disposed in said aperture to bring up against the forward ends of the slotted plates and prevent rearward movement of the tongue with respect to the hounds.
